macOS Native CPU/IGPU Power Management

[toleda]

can you tell if CPU power management is working correctly

iMac14 is not correct for Skylake, see Post #1/Settings

So I need to use 17,1? Could this also be why I’m have trouble with sleeping? I’m getting RTC alarm, I know it’s off topic but could this be? And can one simply just change to 17,1? Would this mess with my USB-SSDT?

Yes

Off topic

And can one simply just change to 17,1?

Would this mess with my USB-SSDT?

No

 

[blassley]

Yes

No

Ok so 17,1 with PluginType=yes? Also will this affect my Overclock? And I’ve read that 17,1 affects Nvidia web driver?

Yes

Also will this affect my Overclock?

Post #1 is clear, BIOS/Optimized Default only. After CPU PM is working, add OC.

And I’ve read that 17,1 affects Nvidia web driver?

Unlikely

Yes

Unlikely

How do u know if cpu pm is working? Also it says in post “likely sleep issues” is this usually the case?

EDIT:
I think I got it, here is my files:

also attached is my report files:
Also should I enable Turbo, and speed step in the bios now? I’m confused on this point

 

[x0b]

Yes

IPG shows your system is very busy, not idling. Idle, no CPU load, is 800 MHz.
PM is working.

I guess IPG is confusing because the frequency shows almost flat around 2900 when it's idling and doing nothing, I presume this is when (8) would be selected in AppleIntelInfo. IPG never shows the frequency at 800 MHz. This is why I've assumed power management wasn't working properly.

Anyway, if you say it's ok then that's good enough for me, thanks for your help

 

[toleda]

Also should I enable Turbo, and speed step in the bios now?

Why did you disable?
BIOS/Optimized Defaults enables both.

Asked and answered, see Post #691.
Activity Monitor shows what is running when you say it is idling.

 

[blassley]

Why did you disable?
BIOS/Optimized Defaults enables both.

Yes but I had them disabled before, didn’t know they work with hacks. They are enabled now, everything seems good.
